Notes on MP3 files

MP3 (MPEG 1 Audio Layer-3) is a standard
technology and format for compressing a sound
sequence. The file is compressed to about 1/10 of
its original size. Sounds outside the range of
human hearing are compressed while the sounds
we can hear are not compressed.

Notes on discs

Yo u can play MP3 files recorded on CD-ROMs,
CD-Rs, and CD-RWs.
The disc must be in the ISO 9660*
level 2 format, or Joliet or Romeo in the
expansion format.
Yo u can use a disc recorded in Multi Session*

1

ISO 9660 Format

*

The most common international standard for
the logical format of files and folders on a
CD-ROM.
There are several specification levels. In
Level 1, file names must be in the 8.3 format
(no more than 8 characters in the name, no
more than 3 characters in the extension
“.MP3”) and in capital letters. Folder names
can be no longer than 8 characters. There can
be no more than 8 nested folder levels. Level
2 specifications allow file names up to 31
characters long.
Each folder can have up to 8 trees.
For Joliet or Romeo in the expansion format,
make sure of the contents of the writing
software, etc.

*

Multi Session

This is a recording method that enables
adding of data using the Track-At-Once
method. Conventional CDs begin at a CD
control area called the Lead-in and end at an
area called Lead-out. A Multi Session CD is a
CD having multiple sessions, with each
segment from Lead-in to Lead-out regarded
as a single session.
CD-Extra: The format which records audio
(audio CD data) as tracks on session 1, and
records data as tracks on session 2.
Mixed CD: In this format, data is recorded as
track, and audio (audio CD data) is recorded
as track 2.

Notes

• With formats other than ISO 9660 level 1 and level 2,
fold er names or file names may not be displayed
correctly.

• When naming, be sure to add the file extension
“.MP3” to the file name.

• If you put the extension “.MP3” to a file other than
MP3, the unit cannot recognize the file properly and
will generate random noise that could damage your
speakers.

• The following discs take a longer time to start
playback.
–a disc recorded with a complicated tree structure.
–a disc recorded in Multi Session.
–a disc to which data can be added.

Cautions when playing a disc that is recorded in
Multi Session

data:
Only audio CD data is played back.

• When the first track of the first session is not audio
CD data:
– If an MP3 file is in the disc, only MP3 file(s) play

back and other data is skipped. (Audio CD data is
not recognized.)

– If no MP3 file is in the disc, “NO Music” is

displayed and nothing is played back. (Audio CD
data is not recognized.)

Remarques sur les fils de commande et
d'alimentation

• Le fil de commande de l’antenne électrique (bleu)
fournit une alimentation de + 12 V CC lorsque vous
mettez la radio sous tension.

• Lorsque votre voiture est équipée d’une antenne
FM/AM intégrée dans la vitre arrière/latérale,
raccordez le fil de commande de l’antenne (bleu)
ou le fil d’entrée d’alimentation des accessoires
(rouge) à la borne de l’amplificateur d’antenne
existant. Pour plus de détails, consultez votre
détaillant.

• Une antenne électrique sans boîtier de relais ne
peut pas être utilisée avec cet appareil.

Raccordement pour la conservation de la mémoire

Lorsque le fil d’entrée d’alimentation jaune est
raccordé, le circuit de la mémoire est alimenté en
permanence même si la clé de contact est sur la
position d’arrêt.

Remarques sur le raccordement des haut-parleurs

• Avant de raccorder les haut-parleurs, mettez
l’appareil hors tension.

•Utilisez des haut-parleurs ayant une impédance de
4 à 8 ohms avec une capacité de manipulation
adéquate pour éviter de les endommager.

• Ne raccordez pas les bornes du système de haut­parleur au châssis de la voiture et ne raccordez pas
les bornes du haut-parleur droit à celles du haut­parleur gauche.

• Ne raccordez pas le câble de masse de cet appareil
à la borne négative (–) du haut-parleur.

•N’essayez pas de raccorder les haut-parleurs en
parallèle.

• Raccordez uniquement des haut-parleurs passifs.
Le raccordement de haut-parleurs actifs (avec
amplificateurs intégrés) aux bornes des haut­parleurs peut endommager l’appareil.

• Pour éviter tout dysfonctionnement, n’utilisez pas
les fils des haut-parleurs intégrés installés dans
votre voiture si l’appareil partage un fil négatif
commun (–) pour les haut-parleurs droit et gauche.

• Ne raccordez pas entre eux les cordons des haut­parleurs de l’appareil.

•RTC (SUB board IC502)
*1) A checking without inserting a memory stick causes an

error, and the “E2PROM NO MS” is displayed.

*2) If the ATA0 (HDD) check results in NG, try to repeat the

check several times.
If repetitional check results in NG, a communication er­ror is doubtful, besides faulty hard disk drive.

*3) A checking without connecting the USB causes an error,

and the “NWWM NG!” is displayed.

4. After automatic check of all items completed, if all items are
OK, “OK ALL” will be displayed. In case of erroneous items,
NG indication is given to respective erroneous items.

5. To return to the DIAG menu, press the left jog button (PUSH
SOUND).

[VERSION DISPLAY]

Besides the version display for the users in normal mode, the ver­sion of each section of the system is displayed.

Procedure:

1. Select the “Test Mode” from the test mode main menu by ro­tating the right jog dial (PUSH LIST), and press the right jog
button (PUSH LIST) to enter the Test Mode.

• Sub (version of sub section)

• CD (version of CD servo section)

[Making CD-R For Service]

At the replacement of parts, this set may require jobs such as ver­sion updating of the main section and sub section and data install­ing to a HDD, and for these jobs, the CD-R for service is needed.
Make the CD-R for service by downloading the data from the “ftp”
server for service. The data to be downloaded are available with
two types, for initial lot type and for upgraded type, and further as
regards the upgraded type, the latest version at that time must be
confirmed, thus requiring extreme care. (See table “The version
of each section” on page 22)

Note on making CD-R: The file format should be ISSO9660.

Store all files in the ROOT directory.

[RELA TING WITH ID]

This set relates the main block (flash memory) and the HDD (hard
disk drive) with a unique ID to protect the copyright.
If the MAIN board or flash memory (IC1030 on MAIN board)
and HDD were replaced, the relationship between flash memory
and HDD is lost, thus causing the HDD to fail. Therefore, the ID
relational work is required.
Perform the work by proper methods, since the work required var ­ies as follows depending on the parts to be replaced.

1) When the MAIN board or flash memory (IC1030 on the
MAIN board) and HDD were replaced at the same time
